PB-39 NiCd	3		6	9	3		6	9

PB-38 NiCd	4.5		7	10	4		7	10

Note:

◆Charge the NiCd battery pack within an ambient temperature of between 5°C and 40°C (41°F and 104°F). Charging outside this range may not fully charge the pack.

◆Repeatedly recharging a fully charged NiCd battery pack, or almost fully charged pack, shortens its operating time. To resolve this problem, use the pack until it is completely discharged. Then recharge the pack to full capacity.

◆If the operating time of a fully charged NiCd battery pack is much shorter than before, the battery life is over. Replace the pack.
